[11] The traces of the Aristotelian theory are quite as apparent in Boschini as in the other Italian writers on art; but as he wrote in the seventeenth century, his authority in this respect is only important as an indication of the earlier prevalence of the doctrine.
The author's conclusion here is unsatisfactory, for the colour of the black races may be considered at least quite as negative as that of Europeans. It would be safer to say that the white skin is more beautiful than the black, because it is more capable of indications of life, and indications of emotion. A degree of light which would fail to exhibit the finer varieties of form on a dark surface, would be sufficient to display them on a light one; and the delicate mantlings of colour, whether the result of action or emotion, are more perceptible for the same reason.
The author appears to mean that a degree of brightness which the organ can bear at all, must of necessity be removed from dazzling, white light. The slightest tinge of colour to this brightness, implies that it is seen through a medium, and thus, in painting, the lightest, whitest surface should partake of the quality of depth. Goethe's view here again accords, it must be admitted, with the practice of the best colourists, and with the precepts of the highest authorities.—See [Note C].
NOTE AA.—[Par. 732.]
Ample details respecting the opinions of Louis Bertrand Castel, a Jesuit, are given in the historical part. The coincidence of some of his views with those of Goethe is often apparent: he objects, for instance, to the arbitrary selection of the Newtonian spectrum; observing that the colours change with every change of distance between the prism and the recipient surface.—Farbenl. vol. ii. p. 527. Jeremias Friedrich Gülich was a dyer in the neighbourhood of Stutgardt: he published an elaborate work on the technical details of his own pursuit.—Farbenl. vol. ii. p. 630.
NOTE BB.—[Par. 748.]
Goethe, in his account of Castel, suppresses the learned Jesuit's attempt at colorific music (the claveçin oculaire), founded on the Newtonian doctrine. Castel was complimented, perhaps ironically, on having been the first to remark that there were but three principal colours. In asserting his claim to the discovery, he admits that there is nothing new. In fact, the notion of three colours is to be found in Aristotle; for that philosopher enumerates no more in speaking of the rainbow,[1] and Seneca calls them by their right names.[2] Compare with Dante, Parad. c. 33. The relation between colours and sounds is in like manner adverted to by Aristotle; he says—"It is possible that colours may stand in relation to each other in the same manner as concords in music, for the colours which are (to each other) in proportions corresponding with the musical concords, are those which appear to be the most agreeable."[3] In the latter part of the 16th century, Arcimboldo, a Milanese painter, invented a colorific music; an account of his principles and method will be found in a treatise on painting which appeared about the same time. "Ammaestrato dal quai ordine Mauro Cremonese dalla viola, musico dell' Imperadore Ridolfo II. trovò sul gravicembalo tutte quelle consonanze che dall' Arcimboldo erano segnate coi colori sopra una carta."[4]
